Hibeads.com Show You Contemporary Fashion Jewelry Using Amethyst

Wednesday, December 30th, 2009

Throughout history, the color purple has been associated with peace, tranquility, and most importantly royalty. It should come as no surprise therefore that through the ages, many kings, queens, and other members of royal families the world over have had a strong preference for amethysts in their jewelry collections. Now hibeads.com would like to show you the fashion jewelry using amethyst…  Royal family and high priests in Egypt and Greece were especially fond of this wonderful gemstone. High quality polished amethysts have been recovered from archaeological sites in Greece and Egypt, providing ample proof to archaeologists and historians of the popularity of amethysts in these ancient civilizations. Catherine the Great and other members of the British monarchy were also very fond of amethysts. There are Biblical references to amethysts, and there is irrefutable proof that Greeks used amethysts for jewelry and adornment as early as 2500 BC.

Amethysts are often associated with life. This is because of their color. They are often associated with violets, some of the earliest flowers to bloom during the spring. People born under the zodiac signs of Pisces and Scorpio consider this stone to be auspicious. It is also considered to be the birthstone for February. The origin of amethyst is quite interesting. The word comes from ancient Greek amethustos, the general translation of which is accepted to be “not to be drunken”. In ancient Greece therefore, people believed that if they consumed alcohol from a cup or chalice of amethyst, they would be immune from inebriation. There is of course, no scientific basis for this claim! Metaphysists believe that this gemstone can control evil thoughts, calm tempers, and make the wearer more insightful and intelligent.

Amethysts are a form of crystalline or macrocrystalline quartz. This term is used to describe quartz where the individual crystals can be seen by the naked eye, as opposed to microcrystalline or crypto-crystalline quartz where the crystals are too small to be seen by the naked eye or even under moderate magnification. Quartz by itself is a colorless mineral, and any color seen in quartz crystals (including amethysts) is a result of secondary minerals of impurities. In the case of the amethysts, the secondary minerals are manganese and iron. The purple color of amethyst comes from its manganese content. The intensity of the color of a particular specimen on the other hand, is controlled by its iron content. The higher the iron content, the deeper the color, and more intensely colored stones are generally preferred over light and subtle colored ones.

New Best Friend: Man Made Diamond Jewelry

Friday, December 25th, 2009

There is not doubt about the value of a diamond jewelry. Over the centuries, man are trying to create the perfect synthetic diamond, something that will look like a diamond jewelry on the naked eye.

As early as 1893, there are already attempts in creating substitutes to diamonds. The first attempt to make a man made diamond was done by Frederic Henri Moissan which involved heating charcoal and adding pressure that caused changes from the graphite into a diamond.   But it was 1979 when mass production of diamond imitations became possible.  

De Beers was the first to coin the term, “ A Diamond is Forever” during the 1940s.   With this kind of advertising, diamond became the usual stone for engagement rings.  Before, during 1930s, engagement rings would usually have opals, rubies and sapphires for their stone.  The value of diamonds started to increase, so was the attempts to create a perfect synthetic diamond.

By 1955, General Electric produced small artificial diamonds which where of the same quality as industrial diamonds.  Synthetic diamonds were created by exposing carbon dioxide to heat over a metal surface.  The heat was created or generated by several lasers. Today, they are mass produced with production reaching as much as 100 tons every year.

Here are some lists of diamond imitating stones:  

• Rock crystals or rhinestones are crystallized quartz which can look like a diamond, however, they could get easily scratched.  

• Zircon is another kind of stone which could pose as a diamond.  By exposing the stone to heat, it could turn colorless making it look like quartz and diamond.  Just like rhinestones they could get easily scratched.  
• Cubic zirconia is called the grandfather of artificial diamonds.  As a diamond copy, it is synonymous with low-cot jewelry and not as a decent fashion accessory.  

• Russian diamonds are also cubic zirconia stones.  The difference is that they are of high quality and can cause about $280 per carat.  These stones are usually mounted in metal settings that are worth real stones.

• Moissanite is another kind of stone which is created or made inside the laboratory.  Just like a diamond, it is a hard kind of stone.  Although they are relatively more affordable than diamonds, they are still expensive.  Moissanite tends to give a greenish shade in natural light and may sparkle too much because its light reflection characteristics. These characteristics make it easier for some expert to differentiate a moissanite from a real diamond.

• Another best imitation of the diamond would be from the Diamond Nexus.  The Nexus and the real diamond’s characteristics are so close together.  The Diamond Nexus could cut glass due to its hardness and sparkle and can be just as brilliant as the real diamond.  Because they are just being introduced in the market, they considerably cost lower.

• Gemisis cultured diamond is another diamond copy.  The difference with the real diamond is that they cannot be made into a clear and white color.  

• Other synthetic diamonds would be strontium titanate, artificial rutile and spinel.  

There’s quite a number of synthetic or man made diamonds available.  Buying them is not illegal, but if the jeweller is trying to sell of man-made diamonds as real diamonds, then there will be a problem.  Which is why when buying diamond jewelry always ask for certification. If you would like to buy a nice present for a loved one but would like to stay within budget, then buying man-made diamond jewelry is not a bad idea.
